Church continues to harass my family

I stopped attending this church two years ago because I felt like they were trying to break apart my family. Me and my kid's father have known each other for over 30 years and we're close friends who started dating young. We started getting family counseling through the church. We have 4 kids together and we're married for 18 years. He ended up realizing he was gay and our therapist wasn't a lot of help. She more so shamed my kids dad and he eventually quit going and we divorced. How I saw it is while I was heart broken, he was my best friend and my kids dad so I still wanted to coparent and have a good relationship. We continued therapy. For myself and my kids and the therapist ended up trying to turn both me and my children against their father. She wasn't supportive of a coparent relationship and said I need to try to take my kids from their father. Found out she was telling my kids their dad was evil and has the devil in him and if they don't cut contact they will have the devil in them. She was doing everything in her power to turn my children against their father. It was really intense and I eventually fired her as the therapist. Why we left the church is because I ended up reporting her because she broke doctor client confidentiality and told the pastor who outted all our family issues during a service. Then I find out from my kids dad that he was being harassed by people from the church for being evil. I took us out of that church and things got worse. They started saying very weird things about my ex that weren't true. They had spread rumors that he was HIV positive. Had a porn addiction, was sleeping with men for money. None of those things were true. They had even called his job to tell them he was having sex with men for money. Then my children got roped into it. There was a rumor started by the pastors wife that my daughter (16) had an abortion. It's been two years and they still harass my family. I have blocked so many people from that church and they've gone to say my family is evil. My kids dad started dating and was dating a man publicly and someone called CPS on him with outrageous claims and it became clear who. If they think we are so evil and servants of the devil I don't understand why after two years they haven't left us alone. It's become easier to ignore and died down a lot from the beginning but hasn't stopped completely. It really effected my childrens mental health. Luckily I have them seeing a different therapist and me and my ex coparent well. I'm just emotionally exhausted and tried going to the police but have been told their isn't much they can do....
